Aside from the scrubber cannister the loop bits are the same.
What are the main flavors of the Inspiration?
Classic and Vision.
The Classic has two handsets that display the 3 cell readouts, one for each controller.
The Vision has a single handset with dual cell readouts that includes a dive timer/depth meter.
You can get nitrox and trimix deco software as an option.
The Vision has a HUD mounted on the DSV with 4 LEDs, two per controller.
The Vision offer the TempStick option which lets you know how much of your scrubber has been used.
The Vision allows data to be downloaded (log) and uploaded (upgrades/fixes).
In the latest fix the cell tracking was disabled, so neither electronics currently have that.
